Re: trans issue
The flex plate might have a slightly different bolt pattern from the 700 to the th400. I ran in to that problem with my diesel trucks. You will need to run a switch for the kickdown on the Th-400 too.

Re: trans issue
I think old Rusty C10 has it backwards. The TH400 has no overdrive, so that won't be a problem. The only thing you'll have to add really is the electronic kickdown switch.
